Résumé :	The European VOC directive will dramatically change the coatings market over the next two years. Solventborne alkyd resins as know today will largely disappear. The challenge for the resin producer and paint formulator is to develop alkyd based coatings with minimal solvent levels. With selected and properly formulated surfactants, water can be incorporated in solventborne alkyd based coatings as a dispersed phase to partially replace hydrocarbons. The use of "non-migratory surfactants' as external emulsion stabilisers allows development of low VOC alkyd based coatings with excellent shelf life and film quality.
